Overview
An image is a single file that contains a bootable operating system on it. Images are used to create instances within DreamCompute. For information about creating image files, see the OpenStack Virtual Machine Image Guide. You can then use the DreamCompute dashboard to upload and manage images in your project.
The following describes how to upload, update, and delete an image using the DreamCompute dashboard.
Before you begin
DreamCompute only supports RAW and ISO images.
Make sure the image file that you are trying to upload in the DreamCompute dashboard is not larger than 2–3 GB, as attempting to do so will likely result in an error message.
Large image files can only be uploaded using the OpenStack command line client. For examples, see the following articles:
